  • Hey Fred

    Just wondering what kind of RWHP and RWTQ your formula puts down? I would assume around 600 N/A right? I just went over your super long mod list and was just curious as to what the numbers were from all that work

    600rwHP N/A???..... surely you jest .

    The engine made 500flywheel, and 436rwHP with the T56. With the huge losses of the TH400, its down to 390rwHP.

    The original engine dyno with nitrous (250-shot) was 762 flywheel HP, and 800 lb-ft. With the T56, it was making 670rwHP. We upped the nitrous later (300-shot) to the point where the rwHP was up to 703. We figure it was right at 800 flywheel. With the TH400 conversion, the rwHP is down to 625. They won't even plot the rw torque curve, because the high stall convertor and torque multiplication make the number meaningless.

    It has a lot of fairly beefy parts in it, but the original goal was for a mild N/A street engine that would pass NJ rolling emissions (it did), with a healthy shot of juice for the track. At one point it was set up for a 125-shot first stage for the street, but we gave that up when went to the 300-shot single stage. The cam is a very mild 230/242 114LSA 0.590 lift on both I/E.

    With a really radical cam, I suspect I could push it closer to 600 flywheel, but that's a big step.

      Wow those are still impressive numbers especially because that thing passes New Jersey crazy emissions

      Do you have any future plans for it? Maybe make it a designated track car and say screw emissions? No matter you decide I have to say that thing is one of the cleanest and most well put together f-bods I have ever seen.

      Btw... you got any vids of that beast??
